a) They reproduce asexually b) They are all unicellular
Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parent.
- Single parent involved.
- No fertilization or gamete formation takes place.
- This process of reproduction occurs in a very short time.
- The organisms multiply and grow rapidly.
- The offspring is genetically similar.
In yeast, budding usually occurs during the abundant supply of nutrition. In this process of reproduction, a small bud arises as an outgrowth of the parent body. Later the nucleus of the parent yeast is separated into two parts and one of the nuclei shifts into the bud. The newly created bud divides and grows into a new cell.
